Thanks guys, I marked the t-bar where the motor would hit, then cut off about 1/8" between the lines I marked right in front of the center screw hole. I then used a 5/16x440 screw and low profile nut, now she slides forward with no problems.
I dont understand why Associated or some smart company wouldnt make a t-bar with a slight notch stamped in it ready to mount. It just makes Associated look like they havent done all there homework when it comes to fit and finish.
